Title: Heat sink
Inventor: SAKUTA YASUHIRO
IPC: H01L23/36
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To raise the cooling efficiency at forced air cooling, by retracing the windward end faces of inner fins more than these of both side fins. SOLUTION: On a base 1, a plurality of fins 2 erect parallel in equal pitches. The windward end faces 2a of the inner fins 2 slightly retract more than those of both side fins 2 on the same plane but all the fins have identical shapes and lengths, and hence the leeward end faces of them similarly retract. The end faces of the near center fins retract more than the both side fins in the flow of forced cooling air to reduce the air flowing around the outsides of the fins from the front of a heat sink to increase the air flowing along the near center of the heat sink, thereby improving its radiation efficiency.

Title: Bonding wire
Inventor: KONNO TAKASHI
IPC: H01L21/60
Filed: 1982-01-25
Abstract: PURPOSE:To save material cost without lowering of strength of bonding wire by forming the hollow part within bonding wire. CONSTITUTION:In case a diameter of ordinaly bonding wire having a solid circular cross section is equal to an external diameter of a hollowed bonding wire 1 in this invention and a diameter of hollowed part 2, namely an internal diameter of wire is 1/2 or less of the external diameter, there is no difference of bending strength between these wires. Particularly when a wire is made of a noble metal such as gold and amount of wire used for unit product is large, effect of saving material resulting from the hollowed wire structure of this invention is as much excellent. When comparing wire diameter and volume in case a bending strength of the wires having solid cross section and hollowed cross section (internal diameter is 1/2 of the external diameter) is equal, an external diameter of wire having hollowed cross section becomes larger by about 2% than the diameter of wire having solid cross section, but the volume decreases by about 22%.

Title: Image pickup device
Inventor: KITO SADAO
IPC: G06T1/00
Filed: 1994-01-31
Abstract: PURPOSE:To attain excellent image pickup from a dark part of an object till a highlight part by receiving a light attenuated stepwise at plural image sensors so as to substantially extend the dynamic range of each image sensor. CONSTITUTION:Image sensors IS2, 3 are scanned in horizontal and vertical directions by the operation of a scanning circuit 7 and each image signal is fed to process amplifiers 8, 9. When high luminance reflection takes lace in an object, a level of an image element from the amplifier 8 reaches a switching level, a switching discrimination circuit 10 gives a switching signal to a switching circuit 11, which provides an output of an image signal from the amplifier 9. Furthermore, when a received luminous quantity is decreased and the level of the image signal reaches the switching level or below, the circuit 11 selects a picture signal from the amplifier 8 based on an output from the circuit 10. Thus, the image signal outputted from the circuit 11 is a synthesized output from the sensors 2, 3. As a result, an excellent image without smear and blooming or the like is obtained.
